Olivier Auverlot: "At my work (a universitary computer research laboratory), I'm alone to create all applications and databases. I don't know how I could do all the work without it. It's really a very productive software. I can focus on the database schemas and create quickly the user applications with a minimal amount of code to maintain".
Anley Lafleur: "I cannot wait to start using your exciting product and I am sure it will help me achieve my objectives".

OnPageLoaded

This event occurs after the page is completely loaded from the server. It allows you, for example, to add additional filters to the dataset.

 

Signature:

function OnPageLoaded()

 

Parameters:

This method has no parameters.

 

Example 1

The following code is used in our Schema Browser Demo to filter database objects belonging to the selected database:

 

applyDatasetFilter($this->dataset);

 

Here applyDatasetFilter() is a function defined in the schema_browser_utils.php file as follows:

 

function applyDatasetFilter(Dataset $dataset) {

    if (GetApplication()->IsGETValueSet('database'))

        $value = GetApplication()->GetGETValue('database');

    else

        $value = ArrayUtils::GetArrayValueDef($_COOKIE, 'database');

    if (StringUtils::IsNullOrEmpty($value)) {

        $globalConnectionOptions = GetGlobalConnectionOptions();

        $value = $globalConnectionOptions['database'];

    }

    if (!StringUtils::IsNullOrEmpty($value)) {

        $dataset->AddFieldFilter('Database_name', new FieldFilter($value, '='));

        setcookie('database', $value);

    }

}

 

Example 2

The following code is used to filter countries by life expectancy:

 

// default values

$minLifeExpectancy = 40;

$maxLifeExpectancy = 90;

 

// checking values in the browser address line 

if (GetApplication()->isGetValueSet('minLifeExpectancy') &&

       GetApplication()->isGetValueSet('maxLifeExpectancy')) {

    $minLifeExpectancy = GetApplication()->GetGETValue('minLifeExpectancy');

    $maxLifeExpectancy = GetApplication()->GetGETValue('maxLifeExpectancy');

 

}  // or (if not found) in the session

elseif (GetApplication()->IsSessionVariableSet('minLifeExpectancy') && 

          GetApplication()->IsSessionVariableSet('maxLifeExpectancy')) {

    $minLifeExpectancy = GetApplication()->GetSessionVariable('minLifeExpectancy');

    $maxLifeExpectancy = GetApplication()->GetSessionVariable('maxLifeExpectancy');

}

 

// applying filter to the dataset

$this->dataset->AddCustomCondition(

    "life_expectancy >= {$minLifeExpectancy} ".

    "AND life_expectancy <= {$maxLifeExpectancy}");

 

// saving calculated values to the session

GetApplication()->SetSessionVariable('minLifeExpectancy', $minLifeExpectancy);

GetApplication()->SetSessionVariable('maxLifeExpectancy', $maxLifeExpectancy);
